Abstract (en)

[origin: WO9944207A1] An insulated electric DC-cable having a polymer based insulation system comprising an extruded and cross-linked polyethylene, XLPE, based composition, disposed around a conductor and a method for production of such a cable. The XLPE based composition comprises a polar modification in the form of a polar segment comprising a polar co-monomer having the general formula: CH2=CR-CO-X-(CH2)n-N(CH3)2 or CH2=CR-CO-O-(CH2-CH2O)m-H where n is equal to 2 or 3; m is equal to a number from 1 to 20; R is H or CH3; and X is O or NH. The polar comonomer is introduced into the XLPE composition.
